• DetectionIntelligent Camera Detects Roadside Bombs Automatically

    Roadside bombs are sneaky and effective killers. They are easy to manufacture and hide, making it the weapon of choice for insurgents and terrorists across the world. Finding and disabling these lethal devices is difficult. Dutch engineers have developed a real-time early-warning system. When mounted on a military vehicle, it can automatically detect the presence of those bombs by registering suspicious changes in the environment.

  • Canine detectionDHS S&T Event to Host Innovators, Researchers, Experts on Canine Detection

    Department of Homeland Security (DHS) Science and Technology Directorate (S&T) is inviting innovators, researchers, and canine training experts to learn about funding opportunities in the detection canine field. “We want to reach a broad spectrum of innovators to help us solve our most important detection canine research challenges,” said Don Roberts, S&T’s Detection Canine Program Manager.

  • Security screeningFaster, Smarter Security Screening Systems

    By now, attendees to sporting events, visitors to office buildings, and especially frequent fliers are all quite familiar with the technologies used at security checkpoints. You arrive at the security checkpoint, check your bags, show your ID and maybe your ticket or boarding pass, throw away the coffee or water you’ve been chugging, and then wait in a long line until it is your turn to be screened. The security lines can be inconvenient. S&T and partners are working to help security screening systems, whether at airports, government facilities, border checkpoints, or public spaces like arenas, to work faster and smarter.

  • Explosions detectionDifferentiating Earthquake from Underground Explosion

    Sandia National Laboratories researchers, as part of a group of National Nuclear Security Administration scientists, have wrapped up years of field experiments to improve the United States’ ability to differentiate earthquakes from underground explosions, key knowledge needed to advance the nation’s monitoring and verification capabilities for detecting underground nuclear explosions.

  • Explosives detectorsAssessing Handheld Explosives Trace Detectors

    Individuals who carry explosives or have been involved in bomb making are likely to be contaminated with trace explosives, microscopic particles invisible to the naked eye. Without the right equipment, detecting trace explosives can be challenging for responders and security personnel. Handheld explosives trace detectors (ETDs) can be used to complement bomb-sniffing canines, which are still the gold standard in trace explosives detection. These detectors can be used to find trace explosives on individuals, hopefully preventing a dangerous incident.

  • Airport security Shoe scanner may improve airport security

    The types of shoes you wear when flying matter. And not just shoe types. Size, material, soles and heels are also very important. Why? Shoes can become dangerous vehicles for terrorists’ plots. DHS wants to prevent future incidents, and this is why S&T is working on a millimeter wave technology for screening shoes as part of the larger Screening at Speed Program.

  • Explosive detectionImproving canine detection of explosives

    The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has awarded $564,988 in funding to Auburn University for two research and development (R&D) projects designed to improve the effectiveness and efficiency of canines trained to detect explosives.

  • Munitions700,000 submunitions demilitarized by Sandia-designed robotics system

    More than 700,000 Multiple Launch Rocket System submunitions have been demilitarized since the Army started using an automated nine-robot system conceptualized, built and programmed by Sandia Lab engineers. The automated system was built for the Army’s demilitarization program that aims to dismantle obsolete ammunition and missiles.

  • Landmines detectionBreeding challenges of land mine-finding rats

    Thousands of people – many of them children – are hurt or killed by land mines each year, so finding these devices before they explode is critical. There is a surprising champion of detection: the African giant pouched rat. Native to sub-Saharan Africa, the pouched rats are large – they can grow up to 3 feet long, including the tail – but are still too small to set off the land mines. They have an exceptional sense of smell – they are also used to detect tuberculosis – but scientists know very little about their biology or social structure, and they’re difficult to breed in captivity.

  • Home-grown terrorismSecret Service intercepts explosive devices sent to Clintons, Obama, CNN

    The U.S. Secret Service says it has intercepted two suspicious packages with “possible explosive devices,” one of them addressed to former President Barack Obama and the other to former Secretary of State Hillary Clinton. Within hours, the Time Warner Center in New York, where news network CNN has studios, was evacuated Wednesday morning after a suspicious device was found in the mail room there.

  • Explosives detectionDeveloping new security scanners capable of detecting explosives

    Using a single pixel camera and Terahertz electromagnetic waves, a team of physicists has devised a blueprint which could lead to the development of airport scanners capable of detecting explosives. The researchers have found an innovative way to capture with high accuracy, not just the shape of an object, but also its chemical composition using a special “single point” camera capable of operating at Terahertz (THz) frequencies.

  • DetectionWiFi can detect weapons, bombs, chemicals in bags

    Ordinary WiFi can easily detect weapons, bombs and explosive chemicals in bags at museums, stadiums, theme parks, schools and other public venues, according to a new study. Researchers  demonstrated how this low-cost technology could help security screening at public venues like stadiums, theme parks and schools.

  • Bomb disposalHigh- and low-tech solutions for bomb disposal

    To ensure bomb techs are on the cutting edge of technology as they address evolving threats, DHS S&T created the Response and Defeat Operations Support (REDOPS) program. REDOPS connects the 466 bomb squads of varying sizes and budgets across the country with the tools and information they need to perform their duties better, faster and more safely. They look at a variety of sources—including the commercial marketplace, responder communities and international partners—for high- and low-tech solutions.

  • Passenger screeningWinners announced in $1.5 million Passenger Screening Algorithm Challenge

    DHS S&T and TSA the other day announced the eight winners of the Passenger Screening Algorithm Challenge. The prize competition solicited new automated detection algorithms from individuals and entities that can improve the speed and accuracy of detecting small threat objects and other prohibited items during the airport passenger screening process.

  • ExplosivesReplacing TNT with less toxic explosive

    Scientists have developed a novel “melt-cast” explosive material that could be a suitable replacement for Trinitrotoluene, more commonly known as TNT. TNT was first prepared in 1863 by German chemist Julius Wilbrand but its full potential as an explosive wasn’t discovered until 1891. TNT has been in use as a munitions explosive since 1902.
